The role of Nitrogen in yield Formation and achievement of quality standards in cereals

Abstract

Grain yield nitrogen content of the grain and nitrogen yield of wheat may vary widely from site to site and from year to year under suboptimal growing conditions, as was shown by Benzian & Lane (1979) in their analysis of wheat production between 1954 and 1973 at Rothamsted. Growth and yield of a crop are the result of the interactive response of the plant to dynamic changes in weather and soil conditions and to the interference of pests diseases and weeds. Recent crop physiological research has resulted in a better understanding of the dependence of crop growth and yield on weather conditions and availability of water and nutrients.
